FRANK MILLER, OF PEORIA, ILLIXOIS.

CHECK-ROWER.

SPEGIFIGATION forming part of Letters Patent No. 287,953, dated November 6, 1883.

-Application filed March 27, 1883. (No model.)

To all whom itvncty concern:

Be it known that I, FRANK MILLER, of Peoria, in the county of Peoria and State of Illinois, have invented an Improved Check- Rower; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which Figure 1 represents a sectional plan through x m,- Fig. 2, sectional side elevation through 3 'Fig. 3, view from beneath of the mechanism separated from most of the parts of the corn'planter.

My check-rower is of that kind in whicha four-armed wheel is intermittently rotated by protuberances on a wire or cord coming in contact with said arms.

My improvement relates more particularly to a means for preventing said four-armed wheel from being rotated at any one movement more than a quarter-circle.

In the drawings, B represents the fourarmed wheel; S, its vertical shaft; M, a beam for holding the upper bearings of said shaft, and also as support for the wire-directing wheels. The plate L, bolted to the under side of the crossbeam I, furnishes the lower bearing of the shaft S. The gear-wheel A, fast on the lower end of the shaft S,-has cast or otherwise secured to its upper side a shallow square box, G. The gear-wheel B is just half the diameter of said gear A, and has its axis depending from the plate L. The crankpin J, set in said gear-wheel B, can slide freely in the slot of the arm H, bolted to the feed slidebar K. The tongue-piece D has at the side of one end a friction-wheel, F, and is provided with a dovetail groove in the under side of the plate L, in which it can slide. The friction-wheel F projects into the said box C, and is pulled-against the sides of the same by means of the spring E, attached to the outer end of the tonguepiece D.

In using this machine, at every quarter turn of. the four-armed wheel It the box 0 turns also with the wheel A, and the side of said box G in contact with the friction-wheel F pulls the tonguepiece D toward the shaft S until said side has turned to a perpendicular position relative to saidtongue-piece D. Then, as the box Oturns alittle more, the pull of the spring E forces said box to complete at once the rest of its quarter-turn, and the wheel F coming to a stop in the next corner of the box 0, the whole machinery is held stationary. Each quarter-turn of the wheel A gives a halfturn to the wheel B, and the crank-pin J of the same communicates to the feed slide-bar K, through the rigid slotted arm H, its alternating rectilinear motion.

What I claim as my invention is as follows:

I. In a check-rower, the tongue-piece D, having friction wheel F and supportinggroove, in combination with a spring, E, the square box G, gear-wheel A, fast thereto, gearwheel B, having crank-pin J and slotted arm II, substantially as and for the purpose specified.

2. In a check-rower, the four-armed wheel R, shaft S, and plate L, having dovetail groove D, in combination with the square box 0, tongue-piece D, having friction-wheel I F, gear-wheel A on said shaft S, gear-wheel B, having crank-pin J, and the slotted arm H, rigidly fastened to the slide-bar K, substan tially as and for the purpose set forth.

3. The shaft S of a check-rower, adapted to rotate intermittently, and the hollow square box 0 thereon, .in combination with the friction-wheel F, tongue-piece D, having groove D, and a spring, E, substantially as and for the purpose set forth.

4. In combination with the shaft S of a check-rower, adapted to rotate intermittently, a square hollow box, 0, fast thereon, and a friction-wheel, F, having means for pressing it radially from the center of said shaft against the inner sides of said box, substantially as and for the purpose specified.

5. The shaft Set a cheelorower, adapted to rotate intermittently, a polygonal hollow box fast thereon, in combination with a fric tion-wheel, F, having means whereby it is pressed radially against the inner sides of said box, substantially as and for the purpose described.

In testimony that I claim the foregoing invention I have hereunto set my hand this 13th day of March, 1883.

FRANK MILLER.
